BURNER CONSTRUCTION.

. Application filed January 23, 1921, Serial No. 440,725. Renewed. July 21, 1922. ScrialNo. 576,628.

To all @071 am t/may concern.

'Be it known that I, ETIENNE Wrrznnnenn, a citizen of the United States, residing at Glendale. Carnegie. in the county oi Allebenyand State of Pennsylvania, have invented new and useful Improvements in Burner Constructions, of which the 'following is a specification.

This invention relates to burners and more particularly .to a burner specially adapted tor use in stoves.

One 01 the main objects of the invention .is to provide a burner of simple construction and operation which may be readily -lormed at small cost. A further object is to provide a burner which may be readily formed from sheet metal and which can burn either oil or gas, or both. Another-object is to provide a burner so constructed as to obtain a maximum supply of air to insure complete combustion this air being utilized for cooling thehurner so as to prevent overheating of the same. Further objectswill' appear from the detailed description.

In the drawings:

Figure 1 is a top plan view of a burner coustrlu'rted in. accordance with my invention, )artly broken away. v

Figure 2 is a side view partly broken away. Figure 3 is a transverse vertical sectional View.

In constructing the burner I provide a main body or casing 1 formed of an upper upwardly tapering section .2 and a lower downwardly tapering section 3, these sections being formed of sheet metal and se eured together at each side by a suitable crimp or head 4-; Body-or casing 1 isclosed ateach end 'by an end plate 5 to "which is secured a screw stud '6 for supporting the burner structure in a stove or heater of suit able type.

An 'oil tank "2' of rectangular cross-section is supported within casing 2 centrally there of and extends to within a short distance of end. plates 5. Thistank is of sheet metal construction and is provided in its top wall with circular depressions 8 each provided with a central opening 9. Depression 8 receives an outwardlyprojecting "flange 10 at with an outer peripheral flange 13 which fits into a circular depression 14 formed in the top of upper section 2 oi casing l, the top 15 of section 2 being flat and provided with perforations 17 surroundlng depressions 14:

this perforated top portion of section 2 forming the gas burner. A perforated cylindrical wick holder 18 is positioned within cylinder 12 and is supported by 'radially projecting wings 19 which rest upon the shoulder at the upper end of neck ll. Each of these wings is provided adjacent to its upper end with an opening for reception oi hook elements at the lower endo'l a suitable bail #20 by means of which the wick holder may be readily removed from the cylinder or oil cup 12 Holder 18 carries a wick2'l of asbestos fiber or other suitable material, the lower portion of this wick beingimmersed in the oil which. is maintained .at a predetermined level within cup '12.

A substantially L-shaped partition member or plate 22 is secured in lower section 3 of casing 1. at each side thereof and extends the full length of casing 1. The top of member 22 is raised to form a top element 23 of substantially inverted U-shape which is provided with openings 24: through its top wall in alignment transversely of casing 1 with the respective oil burners. -Gas is supplied to the gas receiving compartments 25 enclosed by members 22 and the-lateral .wallsof lower section 3 of the casing and escapes into the upper portion of the casing, this gas flowing upwardly and'inwardly along the inner faces of the walls of section 2 and escaping through the perforations 17 whereit'is ignited The gas is supplied to the gas receiving chambers 25 by means of a T26 in the upper end of each arm oi which is secured a tip 27, this tipbeing provided with a reduced neck extending through the bottom of section 3. Oil is supplied to tank 7 by means of asuitable'tube or pipe 28 which may be connected'to a supply tank in any suitable manner.

When the burner is in operation airffiows upwardly through spaces 29 between the sides of tank 7 and members 22 into the upper portion of the casing, this air mixing with the gas so as to insure complete con1husr tion. Ifdesired, the oil burner alone may be used, in which case the air flows through perforations 17 and mixes with the gas generated from the oil producing a blue flameof intense heat. Also, if desired, both the oil and the gas burner may be used simultaneously. In'all three cases, that is when the gas burner is used alone, and the orl burner is used alone, and the gas and ()Il burners are used simultaneously, air will flow upwardly through the spaces 29 and will mix with the fuel, or fuels, being used so as to obtain complete combustion. In addition, this air fiowlng about the oil tank and burner serves to effectually cool the same thus preventing overheating and eliminating all danger of explosion.

A burner constructed in this manner may be readily produced from sheet metal and can be made at very small cost. In addition this burner is of very light construction and may be readily applied to a'heating stove. The burner illustrated is intended more particularly to be used in connection with a sheet metal heating stove of the reflector type, though it will be understood that this burner may be readily applied to either heating or cooking stoves by making any slight changes necessary in details of construction, As will be understood, it may be found desirable to resort to changes in details of construction of the invention, and I intend to include all such variations, as fall within the scope of the appended claims, in this application in which a preferred form only of my invention is disclosed.

What I claim is:

1. In a burner construction, a casing open at its bottom to permit free access of air, oil supply means within the casing and spaced from the side walls thereof, oil burners extending from the top of the casing and communicating with said supply means, the top wall of the casing being provided with perforations surrounding said burners and parallel therewith, and means for supplying gas to the casing.

2. In a burner construction, a casing having its upper portion inclined upwardly and inwardly from each side, a tank within the casing and spaced from the side walls thereof, oil burners depending from the top of the casing and communicating with said tank, the top of said casing being provided with perforations surrounding said burners and the bottom of the casing being open, and means for supplying gas to the caslng.

3. In burner construction, a casing open at its bottom, an oil tank within and extending longitudinally of the casing, oil burners depending from the top of the casing and communicating with the tank, partition members secured within the lower portion of the casing and co-operating with the walls thereof to form gas receiving compartments extending longitudinally of said casing, said members being spaced from the sides of the tank and provided with gas escape openings, the casing being provided with perforations through its top wall surrounding the burners, and means for supplying gas to said gas receiving compartments.

4. In burner construction, a main casing, a tank within the-casing and extending longitudinally thereof, said casing having its top wall provided with depressions and perforations surrounding the same, oil burner casings having their upper ends secured in said depressions and their lower ends secured to the top of the tank and cornmunicating therewith, the main casing being provided at each side of its lower portion with gas receiving compartments in communication with the upper portion of said main casing and spaced from the sides of the tank, the spaces between the tank and said compartments being open at their lower ends, and means for supplying gas to the gas receiving compartments.

5. In burner construction, a main casing having the sides of its upper portion inclined upwardly and inwardly and provided in its top wall with depressions and perforations surrounding the same, an oil tank positioned centrally of and within the casing and disposed longitudinally thereof, said casing being open at its bottom, oil burner casings depending from said depressions and communicating with said tank, and means for supplying gas to said main casmg.

6. In burner construction, a main casing having its upper portion-inclined upwardly and inwardly from each side, and provided in its top wall with depressions and perforations surrounding the same, a tank positioned within the casing centrally thereof and extending longitudinally of the casing, partition members secured in the lower portion of the casing and co-operating with the walls thereof to form gas receiving compartments extending longitudinally of said casing, the inner walls of said members being in parallel spaced relation to the sides of the tank and the spaces between the partition members and the sides of the tank being open at their lower ends, said partition members being provided with gas escape openings through their top walls, and oil burner casings having their upper ends seated in said depressions and communicating at their lower ends with said tank.

7 In a burner construction, a main casing open at its bottom and provided in its to with depressions and perforations surroun ing the same, a tank positioned Within the casing and extending longitudinally thereof, oil burner casings having their upper ends seated in said depressions and provided at their lower ends with reduced necks forming inner peripheral shoulders in the oil burner casings, said necks comnninieating with the tank Wick holders supported upon said shoulders Within the oil burner casings, and wicks carried by said holders.

In testimony whereof I atliix my signature.
